The directive 'review' demands a critical assessment of India's climate trajectory across three timeframes—Paris 2015, COP26 2021, and the 2022 NDC update—rather than mere description. Structure as: brief introduction contextualizing India's climate diplomacy; body in three chronological segments comparing commitments, mechanisms, and ambition levels; conclusion assessing coherence, gaps, and global significance.

• Paris Agreement 2015: India's original NDC targets—reduce emission intensity by 33-35% by 2030 (from 2005 levels), achieve 40% non-fossil fuel capacity, create additional carbon sink of 2.5-3 billion tonnes CO2e through forest cover
• COP26 Glasgow 2021: Panchamrit announcement—net zero by 2070, 500 GW non-renewable energy capacity by 2030, reduce total projected carbon emissions by 1 billion tonnes, reduce emission intensity by 45%, fulfill 50% energy requirement through renewables
• 2022 Updated NDC formalization: emission intensity reduction enhanced to 45% by 2030 (from 2005), non-fossil fuel capacity target raised to 50%, net zero by 2070 made official commitment, removal of reference to 'additional' carbon sink creating ambiguity
• Critical comparison: 2022 NDC quantifies Panchamrit partially but omits explicit 500 GW renewable target and 1 billion tonnes absolute reduction, focusing instead on intensity metrics
• Institutional mechanisms: mention of National Adaptation Communication, State Action Plans on Climate Change (SAPCC), and sectoral missions as implementation frameworks
